Application Bled November 15, 1913. Serial No. 801,158. v

'.To all whom it may concern Be it known `that I, HARVEY BAILEY, a citizen-of the United States, residing at ..Portland, in the county'of Multnomah and State f Oregon, have invented certain new and useful Improvements in Concentrators,

of which the following is a specification.4

This invention relatesA to concentrators,

and has for its object to provide a series of soV `of 'series of-riiiies in suc riie boxes in such relation to each other` that the material to be concentrated will be graded and will be vcaused to gravitate over the series, dropping the heavier particles the raceway for shunting the barren por'l tions of rock from-the device.

Other objects will appear by a reference t0 the specification describing my invention" and to the .drawings illustrating same, in

which-- y Figurel is a side elevation of the complete device,partly in section. Fig. 2 is a front elevation of said device, with hose and valves removed. Fig. 3 is a plan view of a riHe box, with the median portion broken away.

Fig. vvSfis a sectional. elevation on the line B-B of Fig. 7. Fig. 9 is a detail end view of an'iairvpunip, with the cover removed. F-ig. 10 Vis .a sectional elevation on the line D of IFig. 9. Fig. 11 isvan end view of `a slide "plate.. Fig. 12 shows the` method of attaching the slide plate to boxes.

s. Describing the drawings in detail, 1 des-l ignates the hopper of my improved .concentrator, which is made preferably in one with the casing and formed of sheet metal, with a series of protrusions or wings 1 at .each side to form a two-part raceway 4in each of which parts is inclosed a series of zig-.zag sections containing the outwardly inclined nugget boxes 45 :into and over the which the material paes and falls upon the inwardly inclined` grizzlies 45a -supported upon brackets 45", each grizzly be ing provided with a series of openings 47,

to'perrnit the smaller particles to gravitate onto the rilile boxes 23 as they return to the waste will fall, at theY lower'end of each grizzly, .into the pocket screen 54, which rper` race ways in the manner just above de-v scribed. The sections are pivotally sup-Q` ported by means. of pivot pins'O, upon the risers 10. The coarser materials will gravi-.

the tops of which are secured brackets 5 in ,which is mounted a shaft 20. Upon each end of said shaft 20 is mounted a hanger 3,'. -the shank 3a of which is mounted in'the i central portion of the casing 55, where the;

mits the small particles to sift through, to..

gravitate into and throughv the succeeding bearing 2, which is secured to tle'U-beam 4, suitably supported from a frame work.

From the Ubeams,.at each side a bracketk 6, depends to support between the umaer boxes- 45 and the grizzlies beneath, a shaft 21, carrying a drive pulley 22. This shaft passes through the large openings -ln the risers 10. Upon this shaft at a suitable point is fixed an eccentric 19 mountedy in thel strap 19a, to which is connected the-rod 48, which in turn is mounted upon the shaft' 461 This shaft is fixed in the casing 55. y

At a suitable oint upon the main frame,

7 which is directly connected with the reservoirs 8, by means of the outlet 9 and-laterals 52, suitable bearings being formed in they 'at opposingsides in the disk are mounted slide varies in grooves 71,'which vanes a're normally held outwardly by means of compression .springs 77 in the recess 79, formed in. the tongues 7()a of the valves, 'which tongues slide in the recesses 80 so as to yieldg ablybear against thc wall of the .pump asl disk is revolved with its shaft. The

lower series of riflie boxes, grizzlies, etc.' are,

carried upon cross bars 27, which in the' upper portion of each wing, are carried upon sections 11 and 12 to the body of the caslng,

upon the pins 60 and at the outer ends they suitable bearing in the portion 10a; and by me fis of the crank 18 the said brackets may e adjusted to vary theinclination. of the riiiles, etc. carried in the hinged sections of the'race ways. At suitable intervals are disposed upper and lower bars 27 arranged transversely in pairs along each of the inclines, each of said bars being provided at one or both lateral faces with a longitudinal sl'bt 27Il near its inner face adapted to receive the correspondingly formed anges 23 of boxes 23, 24 and 45. At what may be termed the rear ends of said bars are formed stops 34.

In each of the boxes 23 is disposed a series of riiiies 32 mounted upon bearings 32". Each bearing shaft at what may be termed the front end of the box is extended and carries a segment worm gear 29 which meshes ;,with gear shaft 30 mounted in bearings 44,

and operable by means of hand wheel 31, for rocking said riflies upon their bearings. Each of said riiiles is approximately triangular in cross section, with a front face provided with longitudinal scores 32a which serve to inter'- cept `and trap such concentrates as may be blown from the box below, where they will accumulate until their weight will carry" them downward against the current of air. The uppermost face 32- is made in substantially circular form, over which the concentrates will settle presenting their lat sides thereto as seen at 45h, so that the smaller areas will be presented against blasts of air issuing from the box into which they will descend. The third and lower face'32l is extended rearwardly from the pivot point to meetthe rear edge of the face 32e, whereby as the riiiiesare rocked to the rear the spaces between'the riiiles will be enlarged, and when they are rocked forwardly said spaces will be decreased. These movements change the positions of thc faces of the riffles for c0ntrolling the air currents, to aid in trapping the concentrates.

' In the rear end of each box 1s a headed lug 33 to which may be attached the catch 7 8a of the slide plate '7 8, so that as the box is withdrawn to be emptied, or for other purposes, the plate will be drawn into the grooves 27a;

` slide. In the upper bars 27 of each incline is V/ similarly mounted in inverted position'aboxl;

24 corresponding in size and shape to ezfcfhfo the bars it will drop from the catch of the boxes 23; and in each of these boxes 24 is arranged in staggered relation a series of baie plates 39, the edges being provided with a flange 39a. The lower faces of these plates may have a facing of cocoa matting,

on the carpet or other material 41, adapted to colf lect concentrates carriedin the air currents, which escape through the opening 40,/into the carrier 81 which-connects with ho'se 82 leading to outlet 83 inthe discharge outlet of the casing 55. A

In operatlng the machine,'the gravel will be fed into the hopper' 1 whence it will gravitate into the nugget boxes at each side. Power will be applied through the pulley 22 to rotate the shaft 21 and by means of the eccentric 19 a vibratory motionwill be imparted to the casing, vibrating it upon its pivot 69 in the base 17, which accelerates the movei 'ment of the gravel over the nugget boxes and riffles. The disk 72 being fixed upon shaft 21 revolves with it in its casing'7, creating a suction through the intake opening 75 inthe stem 74, which is controlled by the screw cap 76. The air thus taken into the pump is driven out through outlets 52 le ad,

ing from pipe 9 controlled by closure 73, into the pipes 51 which lead to reservoirs 8 formed adjacent the wings l. From these reservoirs pipes 36 controlled by stop cocks 50, lead to the riiile boxes 23 through the ,union 35' and expansion chamber 37, below the riiles 32, between which it escapes to suspend andv carry upward the lighter' portions I of the material, and allowing the heavier particles to drop into'the drawer 38.

42 is a plate covering an idle rilile, for ontrolling the space at the front side of the As the air issues from boxes 23 it passes upf ward through screens 24e into the inverted boxes 247 carrying with it all light particles of concentrates and dust. These currents will be broken up asv they pass between the baille plates 39, and they Will deposit the heavier particles and concentrates uponsaidplates. This action will be faci-litated by means of the dust collector 41 consisting Aof fabric disposed at the farther edge of each plate 39 and on the lower face of the top 24. lThe lighter particles will be conveyed through the pipe' 81 into outlet 83, which action is augmented by an lair blast issuing from nozzle 84 let into said pipe in the-diV rection of the current and leading directly from reservoir 8, thereby creating a partial l l vacuum 1n boxes 24.
